Definition
Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Picrite vs Suevite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Picrite vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Picrite and Properties of Suevite. Learn more about Picrite vs Suevite in the next section. The interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Picrite and Suevite, they have various applications in construction industry. The uses of Picrite in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills. and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Picrite and Suevite
Here you can know more about Picrite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Suevite consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Picrite vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Picrite is Rough and Shiny and that of Suevite is Banded. Properties of rock is another aspect for Picrite vs Suevite. The hardness of Picrite is 6.8 and that of Suevite is 5.5. The types of Picrite are Oceanite whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Picrite is white, greenish white or grey while that of Suevite is light to dark brown. The specific heat capacity of Picrite is 0.88 kJ/Kg K and that of Suevite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Picrite is heat resistant whereas Suevite is heat resistant.
